7.37 USAGE NOTE
A few verbs can be used with a 'to'-infinitive clause to report requests when the hearer is mentioned in a prepositional phrase.
Here is a list of these verbs and the prepositions used with them:
7.38
In ordinary conversation, requests are often put in the form of a question. For example, you might say 'Will you help me?' instead of 'Help me'. Similarly, reported requests often look like reported questions.
When you report a request like this, you can mention both the person receiving it and the person making it.
Alternatively, you can just mention the person making it.
7.39
You can report a request in which someone asks if they can do something by using a 'to'-infinitive clause after 'ask' or 'demand'.
